Suppose an arithmetic expression is given as a tree. Each leaf

Suppose an arithmetic expression is given as a tree. Each leaf is an integer and each internal node is one of the standard arithmetical operations (+, -, *, /). For example, the expression 2 + 3 * 4 + (3 * 4)/5 is represented by the tree in Figure 5.17 (a). Give an O(n) algorithm for evaluating such an expression, where there are n nodes in the tree
